You should always vote based on the content of the debate.
However, some may cross the line into truism territory, which if raised as a debate argument by the contender (with the chance for rebuttals, but they either do not occur or fail), can get the debate declared a troll debate. Votes on troll debates are generally not moderated.
From the extended policies:
Section B: Troll Debates
Subsection B1: Defining Troll Debates
- A troll debate is any
- Competition-style debate (e.g. rap battle, talent show, poetry competition)
- Debate primarily designed to be humorous or facetious or containing primarily humorous or facetious content
- Debate on a truism (e.g. "a bachelor is someone who is unmarried")
This is of courage not to be confused with one side complaining of the unfairness of the other side having better arguments.
A couple examples:
- "The Earth may contain life," is obviously a truism. The may is proven by the very existence of the readers.
- "Winston Churchill may still be alive," the may is lacking obvious support, and a counter argument for the lack of any reason to believe it can easily be made.
